The assessment for the welder’s certificate in the green booklet covers TIG welding; in reality, it refers to argon arc welding (pure argon)

For example, in the case of TIG welding with a requirement of 50% argon, but in practice only argon is used – is this acceptable? ?
Under normal circumstances, in accordance with the requirements of the welding procedure specification, it is necessary to develop a welding procedure plan prior to welding, and to implement strict operational controls during the welding process to ensure that the welding quality meets the specified standards. If the welder’s certificate you have indicates that tungsten inert gas-electric welding is required, but in practice the welding method used is tungsten inert gas welding (pure TIG welding), it is necessary to verify whether the specific welding specifications and procedures allow such a welding method to be employed. If it meets the relevant standards and specifications, then this method can be used for welding. Otherwise, operations must be carried out in accordance with the relevant specification requirements. .
